Abstract: 1,032,020. Rolling. BRIGHTSIDE FOUNDRY & ENGINEERING CO. Ltd., E. N. ALLBESON, and S. R. SKELTON. Oct. 29, 1964 [Nov. 12, 1963], No. 44610/63. Heading B3M. In a mill having working rolls 10 and 12 mounted in chocks 14 and 16 in housings 18 and 20, the upper chocks are urged by a screwoperated cross-head 62 against the adjusting screws for the upper roll. The adjusting screws 28 and 29 (Fig. 3, not shown), are rotatable in fixed nuts 30 and 31 by worm-wheels 34 and 35. Tie rods 56 connect the cross-head 62 to a beam 48 threaded on to an axially fixed screw 42. Rotation of the screw by a worm-wheel 38 thus raises or lowers the beam 48, cross-head 62, chocks 14, and roll 10. Pre-stressed springs 57 in the beam effectively take the weight of the cross-head and roll 10, and a bevel wheel 39 drives a pass indicator 43 from the worm-wheel 38. Motors 92 and 94, or a single motor, rotate the worm-wheel 38 and, when clutches 96 and 98 are engaged, the worm-wheels 34 and 35. To change the rolls, the cross-head and roll 10 are raised by rotating all the wheels 34, 35 and 38 until spacers can be positioned between the chocks 14 and 16. The clutches 96 and 98 are disengaged and the worm-wheel 38 rotated to lower the chocks 14 on to the spacers. A cylinder assembly 77 is then operated to release the cross-head from grooves in the chocks 14 and the roll assembly is moved clear of the housings on a sled 17. Replacement rolls are installed in a similar manner. The apparatus is applicable to 2, 3 or 4-high mills.

In Fig. 9, the filter 23 is mounted in series with a pump 16 of a clothes-washing machine, and the machine is automatically run through a cycle, in which the washing liquid is first circulated from the tub 11 through the filter 23, pump 16 back to the tub, whereby the filter traps lint particles, then the pump 16 is reversed, causing membrane (36) to separate from member (34) so that the trapped lint is flushed out to drain 30, a valve 26, 31 preventing return to the tub. In an alternative arrangement (Fig. 10) not shown, flow through the filter is in one direction for both parts of the washing cycle, but a series of one-way valves ensures that the pump is respectively first downstream, then upstream of the filter. The ridges (59), (60) form a series of arcuate channels (Fig. 5) alternate channels being open to ducts (49) and (50), so that with membrane (36) engaging the ridges flow is constrained through grooves (80) over ridges. Membrane (36) is backed by a flat plate (37) which is spring-loaded (45), but atmospheric pressure also urges membrane (36) down when the filter is upstream of the pump. Ducts (49), (50) are shaped as shown to facilitate connection of resilient hoses 35, 24. Membrane (36) is secured peripherally to member (34) by an encircling steel strap (98).
